Code is structured as follows.
00 .. : Compute the GAMs 1: 'ref' gam with thin plate regression splines (trs) but no spatially varying coefficients. 2: 'basic' gam with spatially varying coeffcients in trs, computed with standardized DF data. 3: 'ns' gam with spatially varying coeffcients in trs, computed with non-standardized DF data. 4: 'sl' gam with spatially varying coeffcients in trs, location centered around 0. N: 'neutral' gam with spatially varying coeffcients in trs, computed on a standardized subsample of the DF data.
01 .. : Examine GAMs prepare_data_and_maps: model_coefficient_maps: clustering_and_predictions:
02 .. : Niche analysis - Variable-specific effects
03 .. : Niche analysis - GAM Optimium
